To design and produce US coins. Contrary to popular misunderstanding, the US Mint does not design or produce US paper currency. That job is the responsibility of the Bureau of Engraving and Printing.
The US Mint continues to produce half dollar coins today although they are seldom seen in circulation.
If you mean a US one dollar Sacagawea coin, only proof and collectors coins sold from the Mint have more than face value. Remember, the coins are made of brass, not gold.
No, if you are talking about the brass coins commonly in circulation. Those coins are only worth $1.
If you are talking about the current US $1 presidential series of coins, no. Such coins are struck in brass and lots of them were minted. Other than finding an error coin, those coins will only be worth $1 for the near (and most likely far) future. If you are talking about a coin set not made by the US mint, those sets very often do not appreciate in value past the value of the metals used to strike them.
Coins are made of brass because brass is a durable and corrosion-resistant metal that can withstand frequent handling. Additionally, brass is a relatively inexpensive material to produce coins, making it a cost-effective option for minting currency.
The U.S. Mint did not produce any 1997 Presidential coins. You may have brass tokens from Reader's Digest magazine that are dated 1997. The tokens have no numismatic value.
None they are brass.

Yes. For example, US $1 coins minted since 2000 are struck in a brass alloy that includes copper, nickel, zinc, and manganese.
No.
All Sacagawea coins are Brass. The US has not had a circulating gold coin since 1933.
The only brass U.S. coins are dollars.
NO GOLD in any circulating US coins, the outer layers of Manganese Brass on the one dollar coins gives them that color.
